50 ton screw compressor water chiller injection molding machine water chiller for plasitc factory
Injection molding chillers are specialized cooling systems used in the injection molding process. They are designed to regulate the temperature of the mold and hydraulic fluid in order to ensure consistent and high-quality production of plastic parts. Injection molding chillers help to remove excess heat generated during the molding process and maintain precise temperature control, which is critical for the proper solidification and dimensional accuracy of the molded parts.
These chillers are typically water-cooled and use a refrigeration system to cool the circulating water or coolant that is then pumped through the mold or hydraulic system. They are equipped with compressors, condensers, evaporators, and other components to facilitate the cooling process. The chillers often feature adjustable temperature settings, flow rate control, and advanced control systems for efficient and reliable operation.
The main benefits of injection molding chillers include improved cycle times, reduced scrap rates, enhanced part quality, extended tool life, and increased overall productivity in the injection molding process. They are available in various sizes and capacities to accommodate different molding machine requirements and can be customized to meet specific cooling needs.
Overall, injection molding chillers play a crucial role in maintaining the optimal thermal conditions during injection molding operations, contributing to the efficiency and success of the manufacturing process.

An industrial cooling water system refers to a system designed to remove heat from industrial processes or equipment in order to maintain optimal operating temperatures. It typically consists of the following components:
Cooling Towers or Cooling Fans: These are used to dissipate heat from the cooling water. Cooling towers use evaporation to cool the water, while cooling fans blow air over the water-cooled surfaces to remove heat.
Water Circulation System: This includes pumps, pipes, and valves that circulate the cooling water throughout the system. The water picks up heat from the industrial processes and transports it to the cooling towers or fans for dissipation.
Heat Exchangers: These devices facilitate the transfer of heat between the cooling water and the industrial processes. They can be shell and tube heat exchangers, plate heat exchangers, or other types depending on the specific application.
Filtration System: To ensure the quality and cleanliness of the cooling water, a filtration system may be incorporated to remove impurities, debris, and contaminants.
Water Treatment System: In some cases, a water treatment system is used to prevent scaling, corrosion, or biological growth in the cooling water system. This may involve the use of chemicals, such as biocides or corrosion inhibitors, and periodic water testing and treatment.
Control System: A control system monitors and regulates the operation of the cooling water system, maintaining proper flow rates, controlling temperature, and managing the overall efficiency and performance of the system.
The industrial cooling water system is commonly used in various industries, including power plants, chemical processing plants, oil refineries, manufacturing facilities, and data centers, to remove excessive heat generated during production processes and equipment operation, ensuring safe and efficient operations.

A water-cooled screw chiller is a type of chiller used for cooling applications that require a large cooling capacity. It is specifically designed to remove heat from industrial processes or air conditioning systems by circulating chilled water through the system.
Here are some key features and advantages of water-cooled screw chillers:
Cooling System: Water-cooled screw chillers utilize a refrigeration system that consists of a compressor, evaporator, condenser, and expansion valve. The compressor compresses the refrigerant, which then flows through the evaporator where it absorbs heat from the process or the air conditioning system. The heated refrigerant is then sent to the condenser, where it releases heat to the cooling water. The water is circulated and cooled in a separate water loop.
High Cooling Capacity: Water-cooled screw chillers are capable of providing high cooling capacities, making them suitable for large-scale applications that require significant cooling capacity. They can handle a wide range of cooling loads and maintain precise temperature control.
Energy Efficiency: Water-cooled screw chillers typically have better energy efficiency compared to air-cooled chillers. The water-cooled design allows for efficient heat transfer to the cooling water, resulting in lower energy consumption. Additionally, water-cooled chillers often have variable speed drive compressors that can optimize energy usage based on the cooling load.
Low Noise Levels: Water-cooled screw chillers tend to produce lower noise levels compared to air-cooled chillers. The condenser, which is the component generating most of the noise, is located in a separate area with the cooling tower or other water-cooling equipment, effectively reducing noise in the immediate surroundings.
Space Requirement: Water-cooled screw chillers typically require a dedicated cooling tower or external water source for heat dissipation. This design allows for smaller physical footprint compared to air-cooled chillers, which need space for the condenser fan unit.
Reliable Operation: Water-cooled screw chillers are known for their reliable operation and long service life. They are designed for continuous operation and can withstand high ambient temperatures and operating pressures. Regular maintenance and water treatment are essential to ensure efficient and reliable performance.
It's important to note that water-cooled screw chillers require a water source and proper water treatment to prevent scaling, corrosion, and biological growth. They are commonly used in industrial processes, data centers, large commercial buildings, and other applications that demand high cooling capacity and efficiency.
The working principle of the water cooled screw chiller is: When the unit is refrigerated, the compressor sucks the low-temperature and low-pressure refrigerant in the evaporator into the cylinder. After the compressor performs work, the refrigerant vapor is compressed into high-temperature and high-pressure gas.
Enter the condenser through the exhaust pipe. The high-temperature and high-pressure refrigerant gas exchanges heat with the cooling water in the condenser, and transfers the heat to the cooling water, while the refrigerant gas is condensed into a high-pressure liquid. The high-pressure liquid from the condenser enters the evaporator after being throttled and pressure-reduced by the thermal expansion valve. In the evaporator, the low-pressure liquid refrigerant absorbs the heat of the chilled water and vaporizes, so that the chilled water is cooled down and becomes the required low-temperature water. The vaporized refrigerant gas is sucked in by the compressor again for compression, and discharged into the condenser, so that it goes round and round, and circulates continuously, so as to realize the cooling of the chilled water.
The chilled water from the unit enters the indoor fan coils, variable air volume air conditioners and other terminal devices, and exchanges heat with convection air indoors. In this process, the water absorbs the heat of the indoor air (dissipates heat to the indoor air). While the temperature rises, the indoor air temperature drops after passing through the indoor heat exchanger, and is driven by the fan to send it into the room, thereby reducing the indoor air temperature, and the chilled water after the temperature rises reenters the unit under the action of the water pump. Circulation, so as to achieve the purpose of continuous refrigeration.
